3.14 Does Emacs contain a virus?

There have been reports in the past that some virus scanners claim
that the Emacs distribution has a virus. This is extremely unlikely if
you have downloaded Emacs from the GNU FTP site or one of its mirrors
and the GPG signature for it is valid and listed in the GNU keyring,
unless perhaps it is a new release made in the last few days, in which
case you should exercise more caution and report the problem. Past
problems seem to have been caused by virus checkers running into a
buffer size limit when unpacking large tar.gz files for scanning, and
reporting the failure as an “unknown virus”.
